-----------------------------------

             Summary: Support query: g.E().properties().hasKey("xx") & 
hasValue("xx")
                 Key: TINKERPOP-2313
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2313
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.4.3
            Reporter: Jermy Li


Currently, it's OK to filter vertex properties by key/value, like 
g.V().properties().hasKey("xx"),

but an exception will be thrown for query with edge properties filtering:
{code:java}
g.E().properties().hasKey("xx") => XxProperty cannot be cast to Element
{code}
 like:
{code:java}
org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerProperty cannot be 
cast to org.apache.tinkerpop.gremlin.structure.Element
{code}
